Table 1.
Monocular descriptive preoperative data. CMT: central macular thickness; D: diopters; Km: mean keratometry; ERM: epiretinal membrane; FCP: foveal center point; IOP: intraocular pressure; µm: microns; mm: millimeters; mmHg: millimeters of mercury; SD: standard deviation; SE: spherical equivalent; RNFL: retinal nerve fiber layer. * Statistically significant difference.
